Richard Abberbury (1350–1416) was an English politician, Justice of the Peace and chamberlain to John of Gaunt, Duke of Lancaster who served as the MP of Berkshire in 1394 and January 1397.

In the early summer of 1385, Adderbury rode north in the company of the Duke as a member of the army led by King Richard II in person, in what would then become the English Invasion of Scotland of 1385.

Later, in 1386 he had traveled to Portugal in the company off two other English negotiators sent to promote a treaty crucial for Lancaster's plans to invade Galicia.

In this capacity he travelled to Paris in the autumn of 1389 in order to procure safe-conducts from Charles VI for Gaunt's return home overland from Bayonne.

During the 1390s he gravitated towards the royal court, however, and was several times employed on diplomatic missions by Richard II, besides serving as knight of the shire for Berkshire in 1394 and 1397.
